On the other hand the Persians did sometimes forcibly deport rebellious peoples. Take the example of the Ionians deported to Bactria. Perhaps the Spartans would find themselves exiled to Central Asia or maybe Africa? This might actually expand the impact of greek culture.
But the question is a bit weird, the Persians never de-civilized a region. The question almost implies Greeks leaving their cities and becoming nomadic barbarians.
